treewide: replace '---help---' in Kconfig files with 'help'

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

IB: Revert "remove redundant INFINIBAND kconfig dependencies"

Several subsystems depend on INFINIBAND_ADDR_TRANS, which in turn depends
on INFINIBAND. However, when with CONFIG_INIFIBAND=m, this leads to a
link error when another driver using it is built-in. The
INFINIBAND_ADDR_TRANS dependency is insufficient here as this is
a 'bool' symbol that does not force anything to be a module in turn.
